Captain A.J. Duncan, M.A.
Armies, like many institutions, have always struggled with the concept of change. Caught
between the necessity to adapt to technological changes on the battlefield and the temptation
to avoid catastrophic risk through recourse to old tried-and-true methods, nowhere is change
debated as passionately as in armies, navies and air forces of the world. Today, as the Canadian
Army attempts to plot a course for its future development (which is always an ongoing project),
it may be of some use to look to past examples for either inspiration or warnings on how other
armies dealt with the subject.
For one such example, one need not look back more than the interwar period. During that
time, the British Army was trying to adapt to revolutionary
technological changes on the battlefield, specifically in the form
of the tank. While some theorists argued that the impact of
this new weapon of war required a radical rethinking of
strategic doctrine, others attempted to fit this technological
innovation into existing Continental attrition-based theories of
war instead. The success of the latter group and the
dominance of their cavalry concept of tank employment is
one of the major reasons for the losses suffered by the British
Army during the early stages of the Second World War. As the
Canadian Army of today looks toward redesigning itself for the future, it would be wise to payattention to cases such as that of the interwar British Army in order to avoid like mistakes which
could cost it dearly on the battlefields of tomorrow.
Up until the death of Sir Basil Henry Liddell Hart in 1970, the predominant view in military
history circles was that the British Army's defeat in 1940 was due to a large and highly influential
cavalry lobby that fought against mechanization and modernization in the British Army from the
end of the First World War on. As Liddell Hart wrote in hisMemoirs:
Cavalry circles loathed the idea of giving up the horse, and thus instinctively decried the tank.They found much support in the War Office and in Parliament. Wellington's reputed sayingthat the Battle of Waterloo was won on the playing fields of Eton is merely a legend, but it is
painfully true that the early battles of World War II were lost in the Cavalry Club.1
This cavalry lobby was supported by an institutional inertia that was supposedly the result of a
largely unprofessional, lazy, amateurish officer corps drawn from the reactionary British gentry.
However, this was far from the truth. By 1930, only about 11% of British officers were drawn
from what could be called the British gentry, with the vast majority of officers being from what
can best be called Britain's middle class. As for the charge that the Army was largely unpro-
fessional, there existed many professional journals and forums within the British Army where
tactics and doctrine were openly and intelligently debated. In addition to the arm-specific
journals, articles on change flooded into The Journal of the Royal United Services Institute, The

Army Quarterly and even conventional newspapers such as The Times, while in service clubs and
the staff colleges, debates on issues such as mechanization were encouraged. The Army
constantly revised its Field Service Regulations often to the detriment of the cavalry. Far from
being an intellectually stagnant institution, the British Army was constantly re-examining itself
and suggesting change.2 Unfortunately, while the British Army debated and adopted new tech-
nologies into the business of war, what they did not do was radically rethink their overarchingstrategic doctrine to take full advantage of these changes.
Before the Boer War, the British Army paid little attention to developing a coherent, unified
strategic doctrine. Its role was mainly confined to policing the Empire, while the Navy saw to
home defence by dominating the sea. This atmosphere changed after 1906 when British
military failures in the Boer War prompted a series of reforms under the secretary of state for
war, Richard Burton Haldane. In preparation for the deployment of the Army to the Continent,
Haldane opened a number of talks with the French general staff regarding future military
cooperation.3 Lacking any strategic doctrine for a Continental war, the British slowly began to
adopt French views, especially those of Ferdinand Foch. By 1909, statements indicating the
adoption of a strategic doctrine of attrition found their way into the Field Service Regulations.One passage in particular is quite revealing: The defeat of hostile troops is, however, only a
means towards the subsequent destruction of the enemy's main force on the battlefield, and this
ultimate objective must be held in view. Another passage, mirroring Foch's view of war and
the role of willpower, stated that half-hearted measures never attain success in war and lack of
determination is the most fruitful source of defeat. In this way, not only did attrition find its
way into British military thought, but so too did the cult of the offensive.4
Although the Field Service Regulations of 1909 went on to emphasize the role of firepower to a
greater extent than the French did (and in doing so, added a British twist to their newly
adopted doctrine), it laid out a sequence of battle derived from Continental attrition theorists.
In short, the manual stated thatonce the enemy was found,
aggressive offences had to be
launched in order to wear
down his reserves while
gathering one's own. Then,
when the enemy was worn
down enough, a decisive
attack could be launched and
the enemy's army shattered.5
Despite the huge lossessuffered by the British Army
over the course of the First
World War, the British military
establishment still maintained
that the strategy of attrition
was valid. In fact, to some
British officers, the course of the war had demonstrated its validity. Many military conservatives
argued that only difference between the Western Front and earlier Continental wars was the
length and scale of the First World War, and this was due to factors outside of the military's

control such as the increased size of armies, the power of modern defences and the withdrawal
of Russia from the war. One officer, writing in the Journal of the Royal Artillery, wrote that:
Indeed, if we should ever have the misfortune to take part again in a great war we shall have
grounds for congratulations if we find ourselves as well prepared in point of doctrine and
training as we were in 1914.6
The First World War threw Europe into a state of confusion and turmoil due to its destructive
nature. Political and social assumptions that had been considered secure since the French
Revolution began to be questioned in light of the horrors of the Western Front. While some
staunchly defended the European political and social institutions that had existed prior to the
war, others believed that the war had exposed fundamental flaws underlying those institutions
and that the time was ripe to replace them with a new order.7 This trend of questioning the
basic assumptions of European thought also extended to the area of military affairs. While it has
already been mentioned that the British military authorities felt that the First World War had
verified the strategic doctrine of attrition, a very vocal group emerged within the British military
establishment that believed the doctrine of attrition had failed. This group, led by men such as
Basil Liddell Hart and John Frederick Charles Fuller, advanced a new theory of warfare thatviewed the tank and mechanization as a revolutionary instrument that would push aside the
doctrines of attrition and replace them with a more rational way to conduct war.8 In the words
of Fuller:
Today every organized army is faced by the greatest revolution that has ever taken place inthe history of land warfare, a revolution which will parallel and perhaps exceed that accom-
plished by steam-power as applied to warfare at sea. It is true that steam-power led to a vastincrease in the size of armies. but it did not radically change their organisation, for in spiteof weapon improvements their tactics remained much the same.
As during the fifteenth and sixteenth centuries the changes in military organisation andequipment were due to gunpowder, and those during the nineteenth century to steam-powerand chemical science, so in the present century the radical changes must be sought in
gasoline and electric power, which, coupled with high explosives, steam-power and chemistry,cannot fail so completely as to establish a new military dispensation.
It cannot be doubted, therefore, that today we are faced by so rapid a development, orevolution, in administration, strategy, and tactics, and through these in organisation,command and discipline, that this development constitutes a revolution which renders ourexisting art of war obsolete, so obsolete that unless we can grasp what it portends, to rely onit in another war is likely to prove a greater danger than to enter it totally ignorant of militaryvalues.9
Instead of the old way of warfare, Fuller and Liddell Hart sought to establish a new model of
warfare that would minimize the costs to all those concerned. This new model, known amongst
its supporters as the theory of armoured warfare, was characterized by new and different
viewpoints regarding the nature and object of war, the goals and principles of strategy, and the
ideal composition of an army.
The goal of a state, according to Liddell Hart in Paris, or the Future of War, was to guarantee its
citizens an honourable, prosperous, and secure existence. The need for war arose when
another state's policies interfered with this primary goal.10 To this end, Liddell Hart believed that

The aim of a nation in war, is, therefore, to subdue the enemy's will to resist, with as least
possible human and economic loss to oneself.11 This meant that the total or absolute wars
advocated by traditional military thinkers were to be avoided, as they interfered with everyday
life to such an extent that civilization itself was threatened:
The Great War caused the direct sacrifice of eight million livesSo ineffectual was thetreatment prescribed by the military practitioners who were called in that the illness took over
four years to run its course, during which the financial temperature mounted daily Our totalwar expenditure was nearly ten thousand million pounds; our National Debt has increasedtenfold. Moreover, these long years of strain and want so impaired the health of the peoplesthat they fell easy prey to epidemic diseases, and the influenza scourge of 1918 and 1919cost, among the civilian population of the world, more than twice as many lives as were lostin battle.
It is surely clear that any further wars conducted on similar methods must mean thebreakdown of Western civilization.12
Liddell Hart, however, saw no remedy for war in the immediate future. War was the result ofthe imperfections of man and therefore permanently engrained within humanity. Fuller wenteven further, stating that war was not only rooted in the inherent imperfections of man, but alsohad economic foundations over the struggle for resources.13 Both men, therefore, viewed waras a permanent phenomenon that, if unchanged, threatened to overthrow civilization.
As the goal of war was to change another state's policies with minimal cost to one's own state,it therefore followed that the objective of strategy was to subdue the enemy's will to pursue
these policies. This could be done in two main ways. First, the enemy could be attacked in sucha way as to undermine the morale of the civilian population. Liddell Hart believed that if theeveryday life of the enemy's population was adequately disrupted, popular outcry and fear ofrevolution would collapse the enemy government's will. Naval blockade was one means to do
this, as it would interfere with the enemy's food supply and trade.14 However, Liddell Hart,borrowing from Giulio Douhet's writings and his own experiences of Zeppelin attacks, believed
that air attacks employing chemical weapons would be the most effective means of collapsingcivilian morale. Gas, Liddell Hart believed, while incapacitating the civilian population, wouldleave intact the factories and other industrial resources necessary to resume normal activityafter the completion of a war.15 This, in turn, was necessary to help restore peace and normalityin the international system to the benefit of both the victors and losers.
A second method of attack on an enemy's will to resist was through neutralizing his armedforces. Ideally, in accordance with his belief that war should impact as little upon the friendlycivilian populace as possible, Liddell Hart felt that the best possible way to do this was not by
attacking the enemy's force head on in a battle of attrition but by employing a strategy ofdislocation. By striking the enemy in such a way as to upset his mental and physical equilibrium,Liddell Hart hoped to reduce the overall number of casualties by destroying the enemy's will tofight without having to risk a force-on-force attrition-based battle.16 In practice, his indirectapproach involved operations like rapid turning manoeuvres that forced the enemy to changefrontage, movements that paralyzed the enemy's supply lines, and fast advances that threatened
two or three objectives simultaneously. In other words, Liddell Hart believed that armiesshould move along the lines of least resistance and expectation so that the enemy would havedifficulty concentrating his strength at any one point.17 In this way, armoured warfare theoristshoped to paralyze the enemy and wear out his will to fight.

In the opinion of both Liddell Hart and Fuller, the best way to enact this new strategy of
dislocation was through the use of an army built around the strengths of the tank. Although the
tanks of the First World War were limited to slow speeds and were prone to mechanical
breakdown, it was believed that these technological problems would be overcome with time.
Once the tank's speed, radius of action, and shock effect were improved, it could be used to
break through or move around the enemy's frontage and attack the command and logisticalstructures behind the enemy's front. This would cut off front line commanders from their chain
of command, paralyzing military structures from the top down.18 Fuller summarized the system
as follows:
An army is an organism, comparable, like all organisms, very closely with the human body. Itpossesses a body and a brain; its fighting troops are the former, its headquarters and staffsthe latter. In the past the usual process of tactics has been to wage body warfare: one bodyis moved up against the other body and like two boxers they pummel each other until one isknocked out. But suppose boxer 'A' could by some simple operation paralyze the brain ofboxer 'B', what use would all boxer 'B's' strength be to him, even if it rivaled Samson and
Goliath's combined? No use at all, as David proved!
Now apply this to the battle of 1923. The tank fleets move forwardtheir objectivesthe billets of the General Headquarters Staffs. These they capture, destroy, or disperse; whatthen is the body going to do, for its brain is paralyzed?19
Due to the speed and mobility required to break through and destroy an enemy's command and
supply networks, Fuller and Liddell Hart
believed that in the future the traditional
arms such as the infantry, cavalry, and
artillery would play a lesser role on the
battlefield. Both men and their
advocates, however, disagreed as to
what extent the roles of the traditional
arms would be diminished. Fuller and
the advocates of the all tank school
viewed infantry and artillery as being
reduced to a mainly defensive role,
guarding the bases from which tanks
operated.20 Meanwhile a more
moderate school, exemplified by Liddell
Hart, thought that the traditional arms,
if properly mechanized and employed,could assist the tank in its mission.
Liddell Hart envisioned land marines
dismounting from carriers to help clear
fortifications and tank-proof areas such as forests.21 Both schools, however, agreed that the
airplane was to become an essential weapon of war as it would provide tank forces with both
a reconnaissance element and a form of fire support.22
Not only would the creation of a New Model Army based on tanks provide nations with an
effective means to wage war, but it would also provide two further positive effects. First, a

mechanized army built around tanks would be better able to deal with new weapons of war,
specifically aircraft and poison gas. The protection offered by armour rendered the machine-
guns mounted on aircraft ineffective, and tank crews could be protected from gas through the
use of air filtration systems mounted on their vehicles.23 Secondly, and perhaps more
importantly, was the impact mechanized forces would have on the conduct of war as a whole.
Because of its highly technological nature, a mechanized force would be expensive to maintain
and therefore small in size. This, in turn, would reduce the complexity and size of the logistical
networks required to maintain an army. Free from the logistical problems posed by the
deployment of the mass conscript army, commanders could now turn their full attention to
tactics, ultimately saving lives. The large expenses involved with mechanized forces would also
mean the end to conscription, an institution which Fuller and Liddell Hart viewed as detrimental
to the application of reason to war. The large conscript armies, they reasoned, required the use
of propaganda that in turn aroused emotion. This emotion made maintaining rational wartime
objectives next to impossible, shifting the basis for decision-making from reason and logic to
anger and hatred. Finally, because of their reliance on light infantry conscripts, mass armies
were large and immobile instruments of war. This impelled commanders to adopt the strategyof attrition, as manoeuvre was next to impossible.24 Once these armies had been done away
with and replaced by small, mechanized forces, the strategy of attrition and hence the causes of
the horrors of the First World War would melt away as commanders would be free to
implement deep, strategic offensives that could paralyze their opponents by threatening their
headquarter and logistical networks. This would create enough chaos that any resistance from
the enemy's main army would simply melt away. It was this emphasis on strategic penetration,
in addition to their emphasis on tactical penetration, which would set the theorists of armoured
warfare apart from their attritionist peers.25
While debate raged over the subject of mechanization and the tank in the service journals,
experimentation occurred with tanks on exercises. In 1925, a series of large-scale manoeuvreswere held on Salisbury Plain, the first such exercises since the end of the war. During the final
exercise, one of the force commanders, Lieutenant-General Sir Alexander Godley, used his
tanks as a manoeuvre force. Combining his tank battalion with a battalion of motorized infantry
and some artillery elements, Godley moved this force around his enemy's western flank and
attacked his enemy's rear area. Although the attack was deemed a failure by umpires due to
the fact the infantry and artillery components of the force had fallen behind, Godley's attack was
commented upon during the Army's official after action report on the exercise. The report
stated that in comparison to Godley's mechanized force, the remainder of the units employed
in the exercise had demonstrated a disturbing lack of mobility. It also stated that while Godley's
attack had failed, this failure was not due to any mistake of principle but due to the state ofdevelopment of Britain's tank forces. [W]hen our tanks have been improved in type and the
numbers have been increased, it is more likely that their employment for action of this type may
become an accepted axiom. Until that time, tanks were still to be employed as an infantry
support weapon, leading them in on attacks and not operating independently.26
Thus, tanks were an accepted weapon within the British Army. They were not viewed,
however, as necessitating a transformation of the Army's strategic doctrines. The Field Service
Regulations of 1924 verify this: [The] main object to which all other operations are merely
preliminaries, is to close with the enemy and destroy him by killing or capture.27 While
accepting the tank as a new weapon of war, the Field Service Regulations still subordinated it to
-

other arms: the duties of tanks in the attack are (i) To assist the advance of infantry. . . (ii)
Destroy hostile tanks. . . (iii) To exploit a success.28 In his book In the Wake of the Tank,
Lieutenant-Colonel Le Q. Martel confirmed this subordination of the tank to infantry by
stressing the need to have tanks cooperate with infantry at all times.29 Despite evidence to the
contrary during the war, the Field Service Regulations also held that the cavalry was still a
significant force on the battlefield: Armed with lance or sword, it can attack mounted ordismounted, while its armament enables it to act dismounted; thus it can combine fire with
mounted action, and exploit either in attack or defence, the advantages inherent in its
mobility.30 The British Army, therefore, accepted the tank, but as of 1925 was not prepared to
release it from its combat support role or use it to replace the cavalry.
In October of 1925, the secretary of state for war, Sir Laming Worthington-Evans, announced
that the British Army would be creating a special mechanized force in order to find the ideal
form of a mechanized division. To this end, a mixed mechanized force of two battalions of the
Royal Tank Corps (RTC), a brigade of field artillery, a battalion of light artillery, a company of the
Royal Engineers, and a machine-gun battalion were assembled at Tidworth under the command
of Colonel R.J. Collins, an infantry officer.31 Although Fuller had originally been considered forthe post, his somewhat outrageous demands of his superiors led to a scandal where he was
reassigned after threatening to resign from the Army.32 The Experimental Mechanized Force
(EMF) began training as a whole on the 27th of August 1927
after completing conversion training on its new vehicles.
The first series of exercises, designed to ascertain the
qualities of the force, led military commentators to conclude
that mechanization allowed the EMF to perform tasks more
efficiently. The proponents of armoured warfare, however,
were frustrated by what they saw as the inability of
commanders to harness the full capabilities of the force.Covering the exercises for the Daily Telegraph, Liddell Hart
wrote it is questionable whether it [the EMF] has attempted
anything that would not be done by ordinary troops of the
same pattern. Therefore, while mechanized forces could
fight more efficiently, they were still employed in accordance with the strategic doctrine the
armoured warfare theorists felt was detrimental to the nation.33
The next year, the EMF, renamed the Experimental Armoured Force (EAF), participated in
more exercises designed to test its abilities. One exercise in particular caught the attention of
observers, when the EAF was assigned the task of striking at the opposing force's lines of com-
munications while the main body of its army fixed the main body of the enemy. The exercise was extremely successful, with the EAF even performing an opposed river crossing in very
difficult conditions. However, once again the proponents of armoured warfare were frustrated
by what they perceived as the lack of vision of the force's commanders. Liddell Hart complained
that Collins, by describing the operation as a raid, had underrated the effectiveness of such
operations.34 Had the EAF been more aggressively employed and larger, Liddell Hart declared
that, far from being an inconvenience to the enemy, this raid would have been decisive. [T]he
armoured force must be expanded to effective proportions. If it is kept a mere toy, training in
proportion to the whole, it will not have the power to achieve more than raids, damaging, but
hardly decisive.35 This was in direct opposition to Lieutenant-General Burnett-Stuart, whose
The successes of the EAF
during these exercises
led the British Army to
adopt what became
known as the cavalryconcept of armoured
forces.

memorandum on the subject (and later the Army's official conclusion) concluded that the EAF
was essentially restricted to the role of a raiding force and not a decisive force in its own right.36
The successes of the EAF during these exercises led the British Army to adopt what became
known as the cavalry concept of armoured forces. This concept viewed tanks and tank forces
as merely the heirs to mounted cavalry and not as a decisive force in themselves. According to
the concept, heavy tanks were best employed as heavy cavalry was during the Napoleonic era:
as a shock force used primarily for raiding and assisting infantry assaults. Light tanks, like the
light cavalry, were to be employed as a screen or for reconnaissance. Although the cavalry
concept did accept the possibility of using tank forces to flank an enemy and strike at his rear
areas, this was only done to cause damage, not as a means to reach a decision. Decision, con-
servatives argued, would come from tank-supported infantry attacks on the enemy's main
force.37
Despite the spread of the cavalry concept within the Army, converts to the theory of armoured
warfare still put forward their ideas. In 1929 Charles Broad, a career soldier, published what
became known as the Purple Primer, a manual describing Liddell Hart's and Fuller's theories while putting forward his own ideas regarding the organization of an armoured force. The
Primer also proposed a series of battle drills for armoured units, many of which are still recog-
nizable today.38 Broad was given an opportunity to test his theories in 1931, when he was given
command of the newly formed (and temporary) First Brigade RTC. After drilling his brigade in
battle drills at the battalion level, Broad conducted a brigade exercise that was very successful.
Unfortunately, very few people took notice of his success.39
In 1934, P.C. Hobart, an experienced tank commander and proponent of the theory of
armoured warfare, was given command of the now permanent First Brigade RTC. After a series
of successful training exercises near the end of 1934, the brigade was combined with
mechanized units of the 7th Infantry Brigade and designated the Mobile Force for a finalexercise under the command of George Lindsay. Convinced that the tank brigade's recent
successes had blinded it to its own weaknesses and concerned about the morale of the non-
mechanized units involved in the exercise, Lieutenant-General Burnett-Stuart, the exercise
director, decided to place a number of restrictions on Lindsay's plans which deliberately

highlighted the mobile force's weaknesses. Lindsay had the added disadvantage of having just
assembled his staff for his new force only a few days earlier. The end-result of the exercise was
a negative one for armoured warfare enthusiasts. Lindsay's force, compelled to move during
daylight hours because of Burnett-Stuart's restrictions, was discovered by aerial reconnaissance
and attacked on its way to its objectives by aircraft. When ordered to withdraw, Lindsay
encountered further difficulties as the opposing force commander, using his few mechanizedunits, blocked Lindsay's line of retreat based on information available to him from aircraft.40
In his critique of the exercise, Burnett-Stuart criticized Hobart and Lindsay for being too
dismissive of the enemy's abilities and for not dispersing their formations in light of the threat of
air attack. He also chided them for being too tied to a vulnerable supply tail. He did, however,
congratulate them for doing their utmost in the face of his difficult restrictions.41 Unfortunately,
Burnett-Stuart's debrief was not made public and led to two results. First, it led to accusations
that Burnett-Stuart had deliberately sought to sabotage all chances of success for the mobile
force due to his own personal beliefs. The long-term effect of this action, according to Liddell
Hart, was that he created a negative attitude in the Army towards mechanization and armoured
formations just as Germany was beginning to expand its own armoured forces. This interpre-tation seems to be somewhat exaggerated, as it is doubtful that even if the Army had whole-
heartedly adopted the idea of the Mobile Division (based on Lindsay's Mobile Force), it would
not have been able to match Germany armoured division to armoured division by 1939. The
second effect of the exercise, known as the Battle of Hungerford, was that in the eyes of many
it had proven that an armoured force operating in enemy rear areas was vulnerable and that
therefore the theory of armoured warfare was fundamentally flawed. How could one attack an
enemy's brain when the very instrument of that attack was vulnerable to non-mechanized
forces? The cavalry concept of the employment of armoured forces as well as the strategy of
attrition were therefore strengthened just as Britain began to embark on a project of limited
rearmament.
42
In November of 1933, realizing that the international situation was deteriorating, the British
government established a Defence Requirements Committee (DRC) consisting of numerous
military, treasury, and Foreign Office officials. The committee was tasked to examine the defi-
ciencies of all three services and to establish programs designed to remedy them. The General
Staff of the Army proposed to the committee a plan involving further mechanization and mod-
ernization within the Army at a cost of 40 million.43 This figure, based on what the General
Staff thought the War Office could realistically provide and not on the cost of what was actually
needed, was opposed by numerous cabinet ministers. Earlier that year the British government
had decided on a general policy of defence and deterrence that left the Army in a less than
advantageous position. Should war break out on the continent, the Royal Navy and the Royal Air Force would provide a wall between Britain and the continent, while the RAF would
threaten any potential enemies with strategic bombing. The Army, meanwhile, would provide
anti-aircraft defences and garrisons for overseas possessions.44 Although soldiers argued that
the Low Countries, if lost, would provide any potential adversary with a base from which to
launch air attacks and eventually a cross-channel invasion, their warnings went largely ignored.
In light of its limited role within this policy, the Committee only granted 20 million to the Army
in order to improve itself.45 Therefore, despite the fact that 1933 and 1934 represented the
beginning of a period of rising budgets for the Army, these increasing budgets were still
inadequate to meet all of the Army's needs.

By 1936 more funds were granted to the Army in light of the growing threat of Nazi Germany
on the continent. The majority of these funds, however, went to programs designed to
complete the mechanization of the infantry, signals corps, and artillery instead of upgrading
Britain's tank force. Exercises held within the RTC, meanwhile, demonstrated the need for new
tanks, as mechanical problems due to wear and tear began to impact upon training. Thus in
October 1936 the Chief of Imperial General Staff, General Sir Cyril Deverell, put forward aproposal designed to update Britain's armoured forces. Four specific types of tanks were
requested: a light tank for the cavalry (which was in the process of mechanizing), a cruiser
tank for the RTC designed to replace the old light tanks within the RTC, a new medium tank
exclusively for the RTC, and an infantry tank designed to be employed in the RTC's infantry
support battalions. In total, the proposal called for the production of 2030 vehicles.46
Deverell's plan still did not signify a victory for armoured warfare enthusiasts. Cruiser and
medium tanks, the only vehicles with the range and striking power required to break through
the enemy's lines and strike at his command and logistical systems, only accounted for one-
quarter of the vehicles requested and even then were replacement vehicles and not reinforce-
ments. Light tanks, which were too lightly armoured and armed to perform this task, and heavyinfantry tanks, which were too slow and logistically dependent to move around in the enemy's
rear area, accounted for the remaining three-quarters. Deverell's plan was not to move the
Army from the strategic doctrine of attrition, but to
supplement it with up-to-date equipment.47
In May 1937 a young and energetic politician by the name of
Leslie Hore-Belisha was appointed secretary of state for war.
Although he had been a major in the First World War, he had
little prior experience with military matters and came to rely
heavily on the advice of Liddell Hart, whom he met just after his
appointment. Taking advantage of this opportunity, Liddell Hartbegan to lobby the new secretary to appoint like-minded men
to positions of influence within the War Office, putting the
secretary into conflict with Deverell.48 After purging Deverell over his opposition to the policy
of limited liability, which stressed the need for Britain to avoid any land-based military
commitments on the Continent, Hore-Belisha, becoming self-conscious over his reputation of
being a puppet of Liddell Hart, began to distance himself from the commentator.49 Thus, on the
eve of the Second World War, advocates of the theory of armoured warfare found themselves
scattered throughout the Army and not in positions of high command as Liddell Hart had hoped.
As Liddell Hart was lobbying the new secretary, difficulties began to arise in the area of tank
procurement. Problems with the Treasury over the costs of Deverell's procurement proposal,combined with the complex process of retooling factories to build the new tanks, led to
production problems. Although the light tank model quickly came into service and began
arriving at units, the manufacture of the cruiser tanks had to be halted. This left the British Army
with a large number of light tanks but very few medium or cruiser tanks. This imbalance of
equipment led to the decision to keep exercises during the 1938 training year at the brigade
level and lower, as tanks for the tank brigade and the infantry support battalions had not
arrived.50
The Munich crisis, along with Hitler's occupation of the whole of Czechoslovakia in early 1939,
led to the abandonment of the policy of limited liability and to the formulation of definite plans

for a Continental expeditionary force, as it was determined that the loss of Czechoslovakia, a
French ally, left France at greater risk of invasion.51 Much to the horror of tank advocates, plans
were also made to vastly increase the size of the Territorial and Regular armies and, to this end,
conscription was introduced in April 1939. Liddell Hart viewed the move as a first step
backward to the creation of a mass army and as a threat to the further modernization. Britain's
military and industrial effort was now geared to the production of a mass army instead of to ahigh quality mechanized force.52 To Liddell Hart, Britain threatened to slip back into the same
mass army mentality that had cost it so dearly in the First World War, undoing all the progress
that the tank advocates and armoured warfare supporters had made since 1919.
The mass expansion of the Army had a number of detrimental effects. First, it impaired the
improvement of the mechanized forces already in being as it pushed Deverell's already tardy
procurement plan onto the back burner of equipment acquisitions. By the beginning of the war,
none of the cruiser tanks and only 196 of the new light tanks had arrived. The British
Expeditionary Force's (BEF's) armoured component left for France ill-equipped to meet the
more modern forces of the German Army despite the fact the British had tried to modernize
their tank forces over the previous three years.53
The second result was that a series of large-scale manoeuvres designed to introduce a new generation of high-level officers to mechanized
warfare (albeit of the attritionist mould) had to be cancelled due to a lack of resources. Changes
in equipment since the last large-scale exercise held in 1935 had radically altered British capa-
bilities. Unfortunately, senior officers never got a chance to test or experience these new capa-
bilities. Instead, they were restricted to a series of map exercises of questionable value. Months
later, those officers would find themselves in command of the BEF in France, fighting a war
against an army whose capabilities they did not fully understand.54
The story of Britain's failure to adopt the theory of armoured warfare as operational doctrine
was not one of enlightened reformers fighting a close-minded and reactionary chain of
command. Nor was it a story of tank versus anti-tank factions arguing over whether tanksshould be employed at all. Instead, it was a story of an open-minded army that, through exper-
imentation, arrived at a conclusion regarding tanks and mechanization that fit well into what it
perceived as the sound doctrinal lessons it had validated during the First World War. The British
Army's error was not due to a lack of a pioneering spirit but rather to a lack of boldness in the
area of doctrinal thinking. It refused to take a leap of faith with a new weapon of war and, by
doing so, found itself beaten in 1940. Prior to his victory at Gazala in 1942, Rommel wrote that
It is my experience that bold decisions give the best promise of success.55 Had the British
Army held such an opinion, its performance in May 1940 might have been very different. As we
today struggle with how to transform our army to deal with the wars of the future, it behooves
us to remember this.
